Hopefully you're kidding about isolating yourself from your family and friends. It sounds like you're already doing a 180 and doing a fantastic job at it. I've been reading this entire thread, and you sound like a very strong person to me. I wish I could "go dark" the way you did when you were blindsided by H with that terrible note. I have found that I need to call a friend or family member at least 3-4 times a week, and my H is still living in our home! I also get extremely angry at times and find it difficult to hold my tongue...you seem to do well with that too. I meet with my church counselor (a long time married woman like me)at least once a week. She has been helpful in helping me raise my self esteem but has advised me to ask my H to leave. I can't do that and cry everytime I think of it.
In short, I very much admire the way you're handling your situation and have learned a lot from you and all the people in this thread who posted answers. I am in the process of reading Michele's The Divorce Remedy again and it does help.
